What are some good ways to deal with chronic pain?

I'm in pain 24/7; it feels like my body is rejecting my soul and it's taking it out on everything especially my head. Doctor's either never heard of my condition or they heard of it and want to cut into my brain but gave me a less than 50% chance I'll be better and an 90% chance I'll be worse. Then I meet doctors who think I'm faking just for medication but then they see all my medical documents, CTs, MRIs, EEGs etc and want to experiment with a new drug on me. At this point all I want to do is sleep and I don't care if I wake up.
